Abstract (en)
An apparatus for counteracting vibrations includes a housing (30) for attachment to a vibrating member, first (32) and second (50) bodies being connected to the housing by first (36) and second (55) springs, respectively, with a combined stiffness which defines a resonant frequency at which the first and second bodies oscillate with respect to the housing. Each of the first and second springs include a plurality of rods (40, 59) fixedly connected between a pair of rings (37, 38; 57, 58). A lever (42) engages the first and second bodies to vary a spacing between those bodies when force from an actuator (50) is applied to the lever. The lever action alters the stiffness of the first and second springs which varies the resonant frequency of the vibration absorber.
